Description

Technical Field

[0001] This utility model belongs to the field of camera motherboard technology, specifically relating to a snap-on camera motherboard fixing device for quick assembly and disassembly. Background Technology

[0002] In modern electronic devices, cameras are important image acquisition tools and are widely used in many fields, such as security monitoring, drones, automobiles, and consumer electronics. With the continuous advancement of technology, the functions of cameras are constantly being enhanced and their size is gradually decreasing. The requirements for their internal structure are also becoming more and more stringent, especially in terms of fixing the camera's motherboard.

[0003] A prior art patent, CN217904493U, describes a coaxial camera motherboard. This patent includes a support base, a motherboard, a first lens, and a second lens. The motherboard is mounted on the left end of the support base, and the first and second lenses are respectively connected to the motherboard. It also includes a support and heat dissipation assembly for guiding the motherboard during installation and for heat dissipation. This assembly is mounted on the support base… This device uses rotating fan blades to blow air onto the motherboard and lenses for heat dissipation, and simultaneously uses an L-shaped air duct to direct airflow onto the motherboard, improving the heat dissipation efficiency of the coaxial camera motherboard. However, in practical use, it still has the following shortcomings: From a practical standpoint, the camera motherboard is directly exposed to the external environment, lacking a protective structure, making it susceptible to intrusion of moisture, dust, dirt, and other substances, which can easily damage the motherboard. Furthermore, most existing camera motherboards are installed using a threaded method, resulting in a small motherboard size that is difficult to manipulate during installation, leading to slow installation progress and affecting assembly efficiency.

[0004] Therefore, a snap-on camera motherboard fixing device is needed for quick assembly and disassembly to solve the problems of the camera motherboard being easily damaged due to direct exposure to the external environment and the low efficiency of the screw-on installation method in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a snap-on camera motherboard fixing device for quick assembly and disassembly, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a snap-on camera motherboard fixing device for quick assembly and disassembly, comprising a mounting plate, two fixing mechanisms on the top of the mounting plate, a camera motherboard detachably mounted on the top of the two fixing mechanisms, two positioning posts fixedly connected to the bottom of the camera motherboard, multiple insertion holes opened on the outer wall of the two positioning posts near the bottom, a protective cover detachably connected to the top of the mounting plate, multiple elastic buckles fixedly connected to the bottom of the protective cover, multiple ventilation holes opened on both sides of the protective cover, and multiple heat dissipation fins fixedly connected to the top of the protective cover.

[0007] The solution specifies that the fixing mechanism includes a fixing sleeve fixedly connected to the top of the mounting plate. Multiple limiting slide rails are fixedly connected to the bottom upper surface of the fixing sleeve. Each limiting slide rail has a slidably connected limiting groove at its top. Insertion pins are fixedly connected to the inner ends of each limiting groove. Guide posts are fixedly connected to the top of each limiting groove. A cover plate is fixedly connected to the top of the fixing sleeve. A turntable is rotatably connected inside the cover plate. Multiple arc-shaped guide grooves are formed on the surface of the turntable. A worm gear sleeve is fixedly connected to the outer wall of the turntable. A concave frame is fixedly connected to the top of the cover plate near its outer side. A worm is rotatably connected to the inner wall of the concave frame. A knob is fixedly connected to the front end of the worm through the concave frame.

[0008] It is worth noting that the ends of the plurality of plug-in heads are all hemispherical, and the outer walls of the plurality of plug-in heads are respectively tightly fitted with the inner walls of the corresponding plug-in holes.

[0009] Furthermore, it should be noted that the multiple guide posts are slidably connected to the inner wall of the corresponding arc-shaped guide grooves, the turntable has a circular opening inside, and the worm gear meshes with the worm wheel sleeve.

[0010] In one preferred embodiment, the top of the mounting plate has multiple slots corresponding to the elastic buckles.

[0011] In a preferred embodiment, a filter screen is fixedly connected to the inner wall of each of the plurality of ventilation holes.

[0012] In a preferred embodiment, all of the heat dissipation fins are T-shaped.

[0013] Compared with the prior art, the snap-on camera motherboard fixing device provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting up a protective cover, it can effectively prevent external dust, moisture, dirt and other substances from entering the camera motherboard, avoid corrosion or short circuit of the motherboard, extend the service life of the equipment, and provide additional physical protection for the camera motherboard, reducing the damage caused by external forces such as collision and scratch to the camera motherboard; at the same time, the elastic buckle and the slot work together to achieve quick installation and disassembly without tools. The locking and releasing function of the elastic buckle allows users to easily fix the protective cover on the mounting plate and quickly disassemble it when needed, saving operation time and labor.

[0015] (2) By setting a fixing mechanism, during installation, the positioning pin is inserted into the fixing sleeve from inside the turntable. Then, the knob is turned to drive the worm gear to rotate, which causes the worm wheel sleeve to rotate and drive the turntable to rotate. This causes multiple arc-shaped guide grooves to push the guide pins to move. Multiple guide pins drive multiple limit slide grooves to move inward at the same time, causing multiple plug-in pins to move inward and be inserted into the corresponding plug-in holes, thereby completing the installation and fixing of the camera motherboard. This replaces the traditional bolt fixing, allowing users to quickly complete the operation without using tools, greatly improving the efficiency of disassembly and assembly.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a snap-on camera motherboard fixing device for quick assembly and disassembly, including a mounting plate 1. The top of the mounting plate 1 is provided with two fixing mechanisms 2. The camera motherboard 3 is detachably mounted on the top of the two fixing mechanisms 2. The bottom of the camera motherboard 3 is fixedly connected to two positioning posts 4. The outer wall of the two positioning posts 4 is provided with multiple insertion holes 5 near the bottom. The top of the mounting plate 1 is detachably connected to a protective cover 6. The bottom of the protective cover 6 is fixedly connected to multiple elastic buckles 7. Multiple ventilation holes 8 are provided on both sides of the protective cover 6. Multiple heat dissipation fins 9 are fixedly connected to the top of the protective cover 6.

[0023] Further as Figure 2As shown, it is worth noting that the top of the mounting plate 1 has multiple slots corresponding to the elastic buckles 7. The slots cooperate with the elastic buckles 7 to lock the elastic buckles 7, thereby completing the detachable connection of the protective cover 6 to the top of the mounting plate 1.

[0024] Further as Figure 1 and Figure 2 As shown, it is worth noting that filters are fixedly connected to the inner walls of multiple ventilation holes 8. The filters can effectively block dust, fine particles and contaminants from entering the protective cover 6, thereby protecting the camera motherboard 3 from contamination and helping to improve the long-term reliability and stability of the equipment.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth noting that multiple heat dissipation fins 9 are all T-shaped. The T-shaped heat dissipation fins 9 can provide a larger surface area. Compared with traditional heat dissipation fins, this design can more effectively transfer heat to the external environment and improve heat dissipation efficiency. At the same time, the T-shaped fin structure helps air to flow between the fins, improves the natural convection heat dissipation effect, and enhances heat dissipation.

[0026] As can be seen from the above working process: by setting the protective cover 6, external dust, moisture, dirt and other contaminants can be effectively prevented from entering the camera motherboard 3, avoiding corrosion or short circuits on the motherboard and extending the service life of the equipment. At the same time, the protective cover 6 can provide additional physical protection for the camera motherboard 3, reducing damage to the camera motherboard caused by external forces such as collisions and scratches. Meanwhile, the elastic buckle 7 and the slot work together to achieve quick installation and removal without tools. The locking and releasing function of the elastic buckle 7 allows users to easily fix the protective cover on the mounting plate 1 and quickly remove it when needed, saving operation time and labor.

[0027] Further as Figure 4As shown, it is worth noting that the fixing mechanism 2 includes a fixing sleeve 201 fixedly connected to the top of the mounting plate 1. Multiple limiting slide rails 202 are fixedly connected to the bottom upper surface of the fixing sleeve 201. Each limiting slide rail 202 has a limiting groove 203 slidably connected to its top. Insertion pins 204 are fixedly connected to the inner ends of each limiting groove 203. Guide pins 205 are fixedly connected to the top of each limiting groove 203. A cover plate 206 is fixedly connected to the top of the fixing sleeve 201. A turntable 207 is rotatably connected inside the cover plate 206. Multiple arc-shaped guide grooves 2 are formed on the surface of the turntable 207. 08. A worm gear sleeve 209 is fixedly connected to the outer wall of the turntable 207. A concave frame 210 is fixedly connected to the top of the cover plate 206 near the outer side. A worm 211 is rotatably connected to the inner wall of the concave frame 210. A knob 212 is fixedly connected to the front end of the worm 211 through the concave frame 210. By setting the fixing mechanism 2, multiple plug-in pins 204 move inward and are inserted into the corresponding plug-in holes 5 respectively, thereby completing the installation and fixing of the camera motherboard 3, replacing the traditional bolt fixing. Users can quickly complete the operation without using tools, which greatly improves the efficiency of disassembly and assembly.

[0028] Further as Figure 4 As shown, it is worth noting that the ends of multiple plug-in heads 204 are all hemispherical. The hemispherical design allows the plug-in heads 204 to better adapt to the shape of the plug-in holes 5, reducing loosening or instability caused by incomplete alignment. Furthermore, the outer walls of multiple plug-in heads 204 are tightly fitted to the inner walls of the corresponding plug-in holes 5. The tight contact surface increases the contact area between the plug-in heads 204 and the plug-in holes 5, making the installation more stable.

[0029] Further as Figure 4 As shown, it is worth noting that multiple guide posts 205 are slidably connected to the inner wall of corresponding arc-shaped guide grooves 208. The arc-shaped guide grooves 208 limit and guide the guide posts 205, and the movement of the arc-shaped guide grooves 208 drives the guide posts 205, causing the guide posts 205 to push the limiting slide grooves 203. A circular opening is provided inside the turntable 207. The design of the circular opening allows the positioning post 4 to be smoothly inserted into the fixed sleeve 201. The worm 211 meshes with the worm gear sleeve 209. The worm 211 has a self-locking characteristic during the meshing process, so that the worm gear sleeve 209 will not automatically rotate in the opposite direction, further increasing the stability of the positioning post 4 insertion.

[0030] This solution has the following working process: In actual use, the positioning pin 4 is inserted into the fixing sleeve 201 from inside the turntable 207. Then, the knob 212 is turned to drive the worm gear 211 to rotate, so that the worm gear sleeve 209 rotates and drives the turntable 207 to rotate. This causes multiple arc-shaped guide grooves 208 to push the guide pins 205 to move. The multiple guide pins 205 drive multiple limit slide grooves 203 to move inward at the same time, so that multiple plug-in pins 204 move inward and are respectively inserted into the corresponding plug-in holes 5, thereby completing the installation and fixing of the camera motherboard 3. After the camera motherboard 3 is installed, the protective cover 6 is picked up and the elastic buckles 7 are inserted into the corresponding slots. The protective cover 6 is installed on the outside of the camera motherboard 3 to provide dust protection.

[0031] In summary: By setting up the protective cover 6, external dust, moisture, dirt, etc., can be effectively prevented from entering the camera motherboard 3, avoiding corrosion or short circuits and extending the service life of the equipment. At the same time, the protective cover 6 can provide additional physical protection for the camera motherboard 3, reducing damage caused by external forces such as collisions and scratches. Meanwhile, the elastic buckle 7 and the slot work together to achieve quick installation and removal without tools. The locking and releasing function of the elastic buckle 7 allows users to easily fix the protective cover to the mounting plate 1 and quickly remove it when needed, saving operation time and labor. By setting up the fixing mechanism 2, multiple plug-in heads 204 move inward and are inserted into the corresponding plug-in holes 5, thereby completing the installation and fixing of the camera motherboard 3, replacing the traditional bolt fixing. Users can quickly complete the operation without the use of tools, greatly improving the efficiency of installation and removal.
